<p>The present invention relates to an improvement of a cap structure of a container which houses a liquid, such as an injection liquid, and is sealed with a sealing member, such as a rubber cork, and in which the opening of said container and the sealing member are covered by a cap. This cap structure of a container, such as a vial, comprises: a metal cap body provided with a hollow annular peripheral wall which protrudes upwards in a part of the upper wall surface of the cap and is open at the top; and a synthetic resin pressing unit which comprises a pressing surface portion with a pressing surface, the rear surface of the pressing surface portion abutting against the abutting surface on the top end of the aforementioned annular peripheral wall. The pressing unit body is fixed inside of the hollow space of the annular peripheral wall, and, below the pressing unit body, the pressing unit has a lower protrusion which presses the sealing member against the elastic force of the sealing member. At least the pressing surface portion is colored a defined color.</p> |
